4. Operating Modes
The hygger aquarium light offers two primary operating modes: Standard Mode (Auto Cycle) and DIY Mode.
4.1 Standard Mode (Auto Cycle)

- Sunrise & Sunset Function: The light gradually ramps up from 'off' to 'on' over a fifteen-minute period, preventing light shock to fish.
- Daylight Mode: Blends white, red, green, and blue LEDs for bright, full-spectrum light.
- Moonlight Mode: Provides 6 single-colored options (red, purple, blue, cyan, green, yellow) and 10 dimmable levels.

4.2 DIY Mode
DIY Mode allows for advanced customization of the light cycle. You can set up to 8 different time slots (L1-L8) with varying intensities and colors. Sections L1-L6 are for full spectrum light, while L7 and L8 are for blue light.
- To activate DIY Mode, press and hold the SET (gear) icon and the LIGHT (bulb) icon simultaneously until the display reads "OFF".
- Use the UP (▲) or DOWN (▼) buttons to switch to "ON" (L1 will appear). Press SET to save.
- For each time slot (L1-L8), set the desired intensity (00-100%) and the begin and end times using the UP (▲) or DOWN (▼) buttons and the SET icon to save each step. Set intensity to "00" to turn off the light for a specific period.
